Two-thirds of the 68 health care companies that went public in 2019 traded above their IPO price by the end of year — many of which provided huge initial returns to owners and outside investors.
The big picture: The vast majority of health care companies that go public are biotechnology firms. Several of those biotechs in the 2019 class benefited from some promising, but extremely early, clinical trial data.
By the numbers: If you bought an equal amount of shares of every health care company that went public last year and then sold before the calendar flipped, you would have gotten a 47% return on your money.
- Sixteen companies saw their stock prices double between their IPOs and the end of the year.
Winners: Karuna Therapeutics made the biggest leap, as the biotech company's stock price almost quintupled by the end of the year. Early clinical trial data showed that Karuna's schizophrenia drug relieved many symptoms, Stat reported.
- NextCure and Turning Point Therapeutics also saw their stocks rise after releasing early-stage drug data.
- Two medical device firms — ShockWave Medical and Silk Road Medical — and fertility benefits company Progyny were the exceptions to the biotech-heavy list.
Losers: SmileDirectClub, which mails teeth-straightening kits, and a handful of biotech startups like Stealth BioTherapeutics saw their stock prices fall by more than half from their IPOs.
The bottom line: Biotech stocks are notoriously fickle. Poor clinical trial data can derail an entire company, and some of these firms inevitably will fail, given the nature of science.
- But the initial signals indicate investors still have plenty of money to throw at health care startups of all stripes.
- Investors also believe many of these biotechs have treatments that will secure federal approval, can be monetized despite broad criticism over high drug prices, and could earn sizable buyouts from larger pharmaceutical manufacturers.
